The Superior Court of the District of Columbia dropped all charges Monday against three activists arrested in August for selling 10-cent cups of lemonade on the lawn of the Capitol building.

Will Duffield, Meg McLain and Kathryn Dill were arrested on Aug. 20 for selling the lemonade as part of National Lemonade Freedom Day — a nationwide protest formed in response to a recent rash of children’s lemonade stands being shut down by police.

Duffield, McLain and Dill pleaded not guilty on Oct. 4 to “sale of goods on U.S. Capitol grounds” — a crime that carries a maximum prison sentence of 180 days. Vending on the lawn of the Capitol is not allowed.
